Spine cutting head: long rod, narrow blade, suitable for intervertebral space operation.

The meniscus suture system is the core instrument for minimally invasive repair of meniscus tears under arthroscopy. The mainstream is all-inside suture (All-Inside). The core is to use high-strength suture with anchor/fixed block to pull and fix the torn flap under the mirror to retain the meniscus function and avoid resection.
1. Core Components (Mainstream Whole System)
Suture device (gun type/cannula type): metal handle + adjustable depth limiting cannula + curved puncture needle (15 °-30 °)+ one-handed trigger for precise puncture, thread feeding and firing of fixed objects.
Implant (core):
Fixed anchor/block: mostly PEEK (polyetheretherketone, biocompatible, radiopaque, high strength), a few are absorbable PLLA/PLGA.
Suture: Ultra-high molecular weight polyethylene (UHMWPE) 2 ‑ 0/0, high strength, low friction, non-absorbable.
Auxiliary: guide needle, cannula, knot pusher, thread cutter.
2. classified by technology pathway (clinical mainstream)
1. All ‑Inside (preferred)
Principle: The whole process is operated in the joint cavity, puncture the meniscus → send the thread → fire the anchor fixed to the meniscus/joint capsule → tighten the closed fissure.
Advantages: Minimally invasive (2-3 3-5mm incisions), no additional incisions, low neurovascular risk, fast operation, fast recovery.
Applicable: Red zone/red and white zone vertical tear, body/back corner, ramp zone, root tear.
Representatives: Smith + Nephew NOVOSTITCH PRO, Ruijian RapidLink Ultra, Su Sheng Biology 360 Series.
2. Inside-outside suture (Inside-Out)
Principle: the needle into the joint through the meniscus, the line leads out of the joint outside the knot fixed in the joint capsule.
Advantages: Fastest fixation, suitable for large/complex tears.
Disadvantages: Posterior medial/lateral auxiliary incision, high risk of nerve injury, large trauma, slow recovery.
Applicable: posterior corner tear, root repair, complex tear.
3. Outer-Inner Stitching (Outside-In)
Principle: outside the joint into the needle, through the skin → joint capsule → meniscus, the line knotted in the joint.
Advantages: Suitable for front corner/body front tear.
Disadvantages: cumbersome operation, fixed strength in general.
Applicable: Front angle tear, simple vertical crack.
Classification of 3. by fixed way
1. Anchor type (most commonly used)
Double PEEK anchor + single suture, vertical mattress suture, strong fixation, not easy to fall off.
Representative: RapidLink Ultra, Su Sheng 360 Series.
2. Full suture anchor (All-Suture)
No hard anchor, fixed by suture knot/loop, small tissue stimulation, suitable for small tear.
Representative: NOVOSTITCH PRO.
3. Absorbable system
Anchor for PLLA/PLGA,3-6 months of absorption, no secondary removal, but slightly lower strength.
Suitable for: young, small tear, sensitive to foreign body.
4. Clinical Key Benefits
Minimally invasive: incision 3-5mm, less bleeding, less pain, short hospitalization (1-2 days).
Meniscus protection: avoid excision, retain shock absorption/stability function, delay joint degeneration.
High healing rate: the healing rate of red area/red and white area repair is 85%-95%.
Convenient operation: one-handed excitation of the whole internal system, 360 ° adjustable and depth limit protection.

Bone cement mixer is a special medical device in orthopedic surgery. Its core function is to mix the powder of polymethyl methacrylate (PMMA) bone cement with liquid monomer evenly, discharge air bubbles as much as possible, control the exposure of methyl methacrylate (MMA) vapor, and provide homogeneous and low pore bone cement for joint replacement, vertebral body shaping (PVP/PKP) and other operations.
